Linkswell makes a 10 inch conversion kit called T Style Radios for Rams. They make a great 12 inch conversion for Fords too. I have one in my F-150. The install to replace my small screen with a 12" screen took about 30 minutes and all connectors and converters were included in the kit, with very specific instructions and videos available.
I did not see a year or specs for your Ram in your signature, so I do not know if the one linked below will work for you. I believe it fits for 2014 to 2018, but Linkswell does update its catalog often, so you may want to call if you have a 2019 or 2020, or see if there is a 12 inch system and kit available and to find out if a conversion kit is available for your specific Ram.
